Firefly
Never be left in the dark
A new era of Firefly begins:
Discreet emergency lighting redefined

Building on two decades of success: The next generation of Firefly has arrived. Experience cutting-edge features in a sustainable, compact design, all protected by a Thorlux warranty of up to 10-years.
A genuine warranty with genuine value
For lasting peace of mind*
Lights. Power failure. Action!
Next-gen optical technology
The right light for the right application
Minimise quantities, maximise spacings, stay compliant
Made to protect people and the planet
Sustainability was a key consideration in the development of the next-generation Firefly, with a 60% reduction in total embodied carbon compared to the previous model. This has been achieved by selecting recycled materials, minimising material usage, reducing energy consumption, and extending the product lifespan.

Small emergency lighting on a big wireless system
SmartScan is a revolutionary wireless lighting management system that maximises energy savings and automates emergency lighting testing and record keeping. The system allows users to monitor their energy performance data and complete operational information for all SmartScan standard and emergency luminaires.
Super reliable Lithium Iron Phosphate battery technology
Longer lifespan
Firefly uses lithium iron phosphate (LiFePO4) battery technology, delivering superior thermal stability, energy density, and charge retention compared to its predecessor, Nickel Metal Hydride (NiMH). LiFePO4 offers double the operational life of NiMH batteries – up to ten years.
Reduced maintenance
The optimised Firefly battery has been reduced in size and weight by over 30% compared to the previous models. Firefly LiFePO4 battery changes will typically be required every 10 years, double that of a NiMH battery.
10 year battery warranty
A market-leading warranty of up to 10 years ensures peace of mind. Thorlux offers a genuine warranty with genuine value – no get-out clauses for the number of burning hours or maintenance, and no convoluted registration process.
Intelligent charging and cell protection
Safety is paramount. LiFePO4 is a specific type of Lithium battery technology approved for use in emergency lighting. Battery pack and individual cell monitoring and protection ensure optimum performance and safety in use. Low self-discharge allows a higher charge efficiency when compared to traditional emergency lighting battery technologies.
Reduced energy consumption
Firefly LiFePO4 batteries use 25% less energy compared to previous-generation NiMH batteries. Furthermore, LiFePO4 batteries consume significantly less energy than traditional nickel-cadmium (NiCd) batteries, saving as much as 60% of energy when replacing older emergency lighting.
Wider operating temperature range
With enhanced performance and a wider operating temperature range, Firefly’s LiFePO4 battery technology delivers greater flexibility across working environments.
Evolving the Firefly: Same DNA, enhanced form
Make light work of installation and maintenance
Installation of the Firefly takes just a few minutes. Its innovative design features a remote gear and battery housing, enabling installation in void depths as shallow as 160 mm.
On-site identification made simple
